Abstract:Continuous development is the theme of our age and it is taken as an ideal form of national economical development by all the countries. The exploration engineering (rock & soil drilling and tunneling), as a part of the geological work that is the commander of an advance vanguard of national economical construction, has inseparable relations with continuous development. This article briefly discussed the relationship of exploration engineering (rock & soil drilling and tunneling) with continuous development and the continuous development of the technique itself.

Abstract:This page has set up a mechanics model and a optimized mathematics model of the working process for the YH-300A Pipe Hammer Using compound model method. Regarding the impaction energy as object number, we can make an optimizing design to the structure. This page also makes a calculation of impaction energy and impaction frequency of the original structure. After the optimize calculation, comparing to the original design the impaction energy has improve at least 19% and the impaction frequency has improve a little. At the same time, we make the finite element calculation to the piston of the YH-300A Pipe Hammer. After the finite element calculation, both the original design and the optimized design have proved the biggest stress located in the vent. And the stress on the impaction side is great. So we should use the finite element method to collate the intension of the body as we use the shock wave method to collate the intention. It can improve the shortage of the using of shock wave method in the intention calculation.

Abstract:The landslide survey in Wushan Erlangmiao Transmigrant Village in Chongqing is one of transmigrant projects in Three Gorges Reservoir Area. The strata within the area are quite complex. Using the traditional drilling methods could not get the landslide investigation goals. While the double core barrel and SM glue mud came out of good results with increasing monthly drilling rate of 150 m to 350 m, core recovery of 85%~90%. The samples from broken rock belts, soft and weak interlayers, slide faces， and clay gravel can be take out by the method.

Abstract:Sample drilling technology is an indispensable technical measurement to regional map-drawing， geophysical and geochemical sampling, paleomagnetism sampling, geological calamity early warning and prevention and control, project site survey.
